To all whom it may concern:

Be it known that I, CARLETON ELLIs,-a citizen of the United States, anda resident of Montclair, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Composi-' tionAdapted for Making Catalyzers, of which the following is aspecification.

This invention relates to a composition intended for use in theproduction of catalytic material'especiallysuch as may be employed inthe hydrogenation offatty oils. The. invention embraces a compound ofnickel or other suitable metallic body of a non-catalytic nature ground'in or mixed with an oil vehicle and capable of yielding catalyticmaterial on heating, with or without the introduction of a reducing gas.

The invention is especially directed to the production of a. compositioncontaining nickel hydrate, nickel carbonate, cobalt carbonate and thelike, preferably free from sulfates, incorporated with mineral oil, pe-

troleum jelly, molten wax and the like, such hydrocarbons beingpreferably free from sulfur, to form a concentrate or putty containingpreferably not more than twenty to fifty per cent. of oil or otherhydrocarbon vehicle calculated on the amount of the nickel compoundemployed. In other words preferably a greater amount of the nickelcompound is used than the oil vehicle.

When nickel hydrate or nickel carbonate is heated in an oil vehicle to atemperature of 350 reduction takes place with the formation of catalyticmaterial. The fineness de pends to a considerable extent on the finenessof the original nickel carbonate or hydrate. When nickel carbonate ispreserved for a considerable time or shipped over long distances it islikely to cake and become too coarse for direct use in making catalyzer.According to the present invention the nickel compound is preferablyground in an oil vehicle such as petroleum jelly in order to secure thathigh degree of fineness which arises from grinding in an oil medium andat the same time eliminate losses by formation of dust. The materialwhen ground in oil does not cake on standing and may be shipped overlong dlstances and to hot climates without deterioration. By us ing amineral oil practically no change takes placein the-vehicle on standmg.

Other oils such as fatty oils may be used Specification of LettersPatent.

in some cases but have a tendency to become rancid which may beobjectionable especlally with certain compounds of nickel.

Organic salts of nickel also may be employed such as nickel acetate,oxalate or formate. In such cases it is possible either to use a drysalt or one which contains water of crystallization and even someoccluded moisture. Such compounds when ground in paraffin oil becomevery fine and retain that degree of fineness indefinitely. Approximatelytwenty to thirty per cent. of the paraflin oil may be employed.

The composition is preferably made up as stated by grinding the nickelcompound with only just enough oil to produce a product of theconsistency of putty or slightly thinner. This may be packaged in cansor casks for shipment. When using it is thinned with an additionalamount of oil which may be fatty oil if desired and heated to thedecomposition point with or without the introduction of hydrogen orother reducing gas. If prepared by heating in mineral oil to a crackingtemperatureit is preferable not to have any fatty oil present but to adda suflicient amount of mineral oil to ive the necessary fluidity forcarrying out t e heating operation. The catalyzer so obtained may bepassed through a filter press to remove the excess oil or the mixture ofcatalyzer with the oil may be added directly to the fatty oil to behydrogenated, provided of course the presence of a small amount ofmineral oil in the fatty oil is not objectionable.

The invention is particularly directed to the use of basic compounds ofnickel such as nickel carbonate or nickel hydrate incorporated with, andpreferably ground with a hydrocarbon vehicle preferably a mineral oilfree from sulfur employing a minor proportion of the latter so as toyield a plastic mass or concentrate of the character of putty and theinvention includesa putty-like composition comprising a basic compoundof nickel.
